摘要:
Disposable laparoscopic surgical instruments for insertion through trocar tubes are disclosed. The instruments broadly include: a hollow aluminum tube; an aluminum clevis which is formed separately from the aluminum tube with the distal end of the hollow aluminum tube crimped around the proximal end of the clevis, and with the clevis including an axially off-set pivot pin; at least one end effector element having a pivot hole through which the off-set pivot pin of the clevis is pivotally engaged, and another through-hole; an aluminum push rod extending at least partially through the hollow aluminum tube and mechanically coupled to the end effector element; and apparatus for imparting reciprocal motion to the push rod relative to the aluminum tube, whereby the reciprocal motion is translated at an offset pivot of the clevis into a high torque pivotal motion of the end effector element.
